backtrace support compiled with more conditions

Browse Source 
following #1356,
only enable backtrace compilation on linux+glibc.

Also, disable backtrace by default from "release" compilation,
so that less platforms get impacted by the new requirements.
Can be manually enabled/disabled using BACKTRACE=1/0.
